Justice system corrupt, says Sica

BREAKING: Minutes after he was convicted of murdering three siblings, Max Sica told a packed courtroom the Queensland justice system was corrupt.

The 42-year-old showed no emotion as a jury delivered three guilty verdicts in Brisbane Supreme Court for the murders of Neelma Singh, 24, Kunal Singh, 18, and Sidhi Singh, 12, at their family home in Bridgeman Downs, in Brisbane's north, on April 21, 2003.

"I didn't kill no one and the Queensland justice system is corrupt," he said when asked if he wanted to say anything.

There were tears from the public gallery when the verdicts were read out.

Shirley Singh, mother of the three siblings, rocked forward when the verdict was read out.

She said, outside court, she was too distressed to speak and would now spend time with her family.

The court had heard numerous allegations about a complicated relationship between Sica and the Singh family.

The Crown had alleged Neelma had been in a relationship with Sica and wanted to break it off.

Sica has always maintained his innocence.

Sica will be sentenced on Thursday at 10am.

The QPS have been in contact with the Singh family and they have requested their privacy be respected at this time.

The family has expressed an intention to speak to the media in the future.
